const-tweaker

Tweak const variables live from a web GUI.

This library opens a web interface when the application is run, allowing you to change the values of constants in real time. It's especially useful for gamedev where you want to tweak some variables without introducing a hot-reloading scripting language for it.

Example

const_tweaker::tweak! {
    VALUE: f64 = 0.0;
}

fn main() -> Result<(), Box<dyn std::error::Error>> {
	// Initialize the server at 'http://127.0.0.1:9938'
	const_tweaker::run();

	// Enter a GUI/Game loop
	loop {
		// ...

		// Print the constant value that can be changed from the website.
		println!("VALUE: {}", VALUE);
	}

	Ok(())
}
